Go out immediately. We are not saying you should drink.
I'm suggesting this for your own good and social well being.
If you are knackered have a red bull or coffee.
Seriously, don't do this to yourself. It's borderline tragic!
I don't see how not going out at night, when I've spent rest of the day at the freshers fair/student union, chatting to my room mates about where they come from, what course they are doing and going around the town/city is boderline tragic.
Sorry I just don't.
